Pioneer AVIC-S2 RU - Manual (Page 68)

5.6.5 User data management
Everything that was saved (pins, My POIs, Favourites, track logs etc.) or modified
(Settings, History lists) since AVIC-S2 was installed is stored in a user database
located in the internal memory of the AVIC-S2. Here you have options to save,
restore or reset the database or parts of it.
5.6.5.1 Backup Data
You can make a safe copy of the whole user database on a memory card.
Tap this button to copy all user data and settings on the memory card. The backup is
always created with the same file name; so backing up data will always overwrite
previous backups.
Tip: If you wish to keep more versions of the user database, or you wish to save one
particular state (e.g. saved POIs and track logs of your holiday), look for the backup
file on the SD card, rename it, or save it to your PC.
5.6.5.2 Restore Data
If you have accidentally deleted things, or you have created a number of temporary
items and you do not wish to delete them one by one, you can tap this button to
restore the state of AVIC-S2 to the latest backup.
By tapping this button you will lose all of the changes made since the time of the
latest backup. AVIC-S2 will warn you about this before overwriting the current
database with the backup.
5.6.5.3 Clear Data
This button will delete all user data. It is a reset to factory settings. Tapping this
button means you lose all your saved data and customised settings. AVIC-S2 will
warn you about this.
